Joule's Law

Is there anywhere I can get a graph of joule's law? You can get the experiment at sei.ie but no graph. It's the the end result of the experiment where you test for heat from a metal coil with a certain current flowing through it Thanks

If you're using P=(I^2)R, I'm guessing you'll put I^2 on the x axis (since you choose the current) and P on the y axis (since this depends on the current you chose), in which case, you're going to get a straight line through the origin?
